Public Health England has also put together an online quiz to give people a personalised health score. More than one million people have taken part so far.

MEC handled the media planning for the campaign, and Carat worked on the buying, while Freud Communications has handled PR.

Professor Sir Muir Gray, clinical adviser for the One You campaign, said: "The demands of modern-day living are taking their toll on the health of the nation, and it’s those in middle age that are suffering the consequences most, as their health reaches worrying new levels.

"Over 15 million Britons are living with a long-term health condition, and busy lives and desk jobs make it difficult to live healthily. But just making a few small changes will have significant benefits to people’s health now and in later life."
